WMS 3.1.1 hotfix released. But, be careful!!

Dell has released the WMS 3.1.1 hotfix which should fix the password issue.

However, it looks like that in most cases the hotfix kills your WMS install. After the install, Tomcat does not start anymore. You would have to copy a backup version of the server.xml afterwards to get it up and running again.

But, even if you get it running, some of you and some others have reported that the initial issue is not resolved.

I will keep you updated if any news gets available. Until then I would highly recommend to NOT install that hotfix.

ThinOS 9.1 Release

It is this time again. A new ThinOS version was released today.

However, this time it is not just the next version. With ThinOS 9.1 we finally have a full ThinOS back with support for all current VDI protocols and environment.
While ThinOS 9.0 was only supporting Citrix environments, ThinOS 9.1 now supports Citrix, Microsoft, VMware and even Amazon Workspace backends.

The new version will be available for all current models, 3040, 5070, 5470 AIO and 5470 Mobile. It will run on ThinOS and ThinOS+PCoIP devices.

Beside the fact that all backends are supported now, there are a couple of more enhancements.

Here is a comprehensive list of new features:

Technical Problems

I am really sorry but I have some technical problems with this website.

This results in several e-mails that have been sent out to you. I am already working hard on this and hope to get this resolved soon.

UPDATE: Looks like the technical issues are resolved. In the meantime I got more than 40000 unwanted emails and my mailbox nearly exploded.
Again, I am very sorry for this to happen.

DSA-2020-281: Dell Wyse ThinOS 8.6 Security Update for Insecure Default Configuration Vulnerabilities

As more and more articles popping up about the “security issue” I thought it would be good to give you some insights about it.

Prof. Gil David and Elad Luz of CyberMDX reported two vulnerabilities (CVE-2020-29491 und CVE-2020-29492) to Dell some days ago and Dell took immediate action by releasing ThinOS 8.6 MR8 which fixes this vulnerability.

So far so good. However, is this really such a big security issue? Should you hurry and update all clients to be safe again?

This depends on how you are managing your ThinOS clients. If you are still using a standard FTP or HTTP server with anonymous access and read/write permissions then the clear answer is YES. Run boy, run!

But, if you are using any kind of SSL encryption, for example, HTTPS protocol, without write permissions to the WNOS share then you are safe.
The same applies if you are already using Wyse Management Suite (WMS) for managing your Thin Clients.

Conclusion: In my opinion, this is a valid security issue to point on. However, Dell never recommended using plain FTP with anonymous access and full permission. Every administrator should know that this would open all doors wide open for every hacker.
Therefore, they recommend for a long time already to rely on HTTPS or even WMS.

ThinLinux 2.x for Wyse Thin Clients Transition

Overview: What’s happening?

Dell’s ThinLinux 2.x operating system will go End of Marketing Life on January 31, 2021, and End of Service Support on April 30, 2021. Current ThinLinux 2.x customers with Wyse 3040, 5070, and 5470 thin client endpoints can expect the following:  

Available Options:

Wyse 5070 – Dell Hybrid Client (DHC) conversion kit is available to migrate customers to Dell Hybrid Client (DHC) 1.1.

This option is scheduled to be released 8th of December 2020 and is based on Ubuntu Linux 18.04. Subsequent releases of DHC will be based on Ubuntu 20.04.

ThinLinux customers with Wyse 5070 configurations with 16 GB eMMC and 4 GB RAM, will only be able to migrate to DHC 1.1. Due to minimum configuration requirements for DHC 1.5 with Ubuntu 20.04 of 32 GB storage, customers with 16 GB eMMC will not be able to receive upgrades beyond DHC 1.1.

Ubuntu 18.04 will EoML on April 2023.

DHC is offered as a subscription service managed with Wyse Management Suite (WMS) Pro for DHC.

There is no migration path for Wyse 3040 and 5470 mobile thin client.

Wyse Management Suite 3.1 release

I am excited to announce that the new Wyse Management Suite 3.1 is about to be released soon.

The public cloud update for customers with US1 subscription, will begin on Friday, December 4th, at 7:00 pm PT and is expected to last 8 hours.

Customers using Wyse Management Suite Pro Cloud with EU1 subscriptions should expect it to be unavailable for 8 hours on Saturday, December 11th, 2020 from 4:00 am to 12:00 pm CET.

During this time, the portal will be unavailable and users will be redirected to a maintenance page. There may also be brief periods when the maintenance page is unreachable. However, this will not affect the Thin Clients’ ability to connect to their computing environments.

Customers using the on-prem version, can download the WMS 3.1 version here from December 4th, 2020.

Wyse ThinOS 8.6 Maintenance Release 7 is now available

This week Dell released the next update for ThinOS 8. It is version 8.6_511 or the so-called Maintenance Release 7.
Actually, this release wasn’t planned to get released that early. However, due to the bug that PCoIP wasn’t working anymore after upgrading to 8.6_412, the code was released earlier.
Also worth noticing is that this release is only for 3040, 5010, 5040, 5060, 5070, 5470, and 7010.
Support for older units like 3010, 3020, 3030 was removed.
